Code #1 : nodes() Example

# Python code explaining
# SymPy.Prufer.nodes()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer

# Using from
# sympy.combinatorics.prufer.Prufer.nodes()

# Creating Prufer
a = Prufer([1, 2, 3], [2, 4, 5])

# nodes value
print ("Prufer a nodes : ", a.nodes)

Output :

Prufer a nodes : 5
